<h3 id="rationale">Rationale:</h3>
<p>The intent was to run the code in the single quotes. This would have
worked with slanted backticks, <code>`..`</code>, but here the very
similar looking single quotes <code>'..'</code> were used, resulting in
a string literal instead of command output.</p>
<p>This is one of the many problems with backticks, so it's better to
use <code>$(..)</code> to expand commands.</p>
<h3 id="exceptions">Exceptions:</h3>
<p>None.</p>
